Description

  The present invention relates to an apparatus for collecting and collecting waste chickens to be collected from a poultry house in a chicken farm by vacuum suction.

“Niwatori” for egg collection starts laying eggs 5 months after birth, and about 15 months thereafter is considered as an economical egg collection period, and it is generally renewed regularly 20 months after hatching. Surviving hens are effectively used as raw materials for livestock feed. Wasted chickens to be recovered include living dead chickens and dead chickens killed in large numbers due to epidemic diseases.
Many large poultry farms are two-story, and each floor is composed of four to six cages (breeding cages) that are housed in units of six, with rows of about 100m in length. The building contains between 500,000 and 100,000 birds. ,
Even if the house is equipped with a ventilation fan, the bad smell and harmful gas generated from the chicken manure are mixed at a high concentration, and the interval between the cages is only about 1m, so the harvesting work of the waste chicken is in a poor environment. It becomes work with danger in. Furthermore, since it is necessary to perform as quietly as possible so as not to give fear to the “chicken” during the egg-collecting period, it is performed exclusively by the chicken house by hand. For this reason, the cost of collecting spent chickens has become considerably high, and there has been a demand from feed suppliers to reduce it.

The present invention provides a harvesting apparatus that eliminates manual capture work, reduces labor and cost of waste chicken harvesting work, can quickly perform safe and hygienic work, and can be applied to a breeding cage of a large-scale poultry house. It can be realized by the recent enforcement of relevant laws and regulations.

The present invention includes a suction hose that travels in a narrow passage between breeding cages and reaches the upper breeding cage, a work cart having a lifting means for workers, a hose reel cart having a hose winding device, and a waste chicken. It is comprised from the suction pump vehicle provided with the tank with a filter to accommodate.
The hose has a diameter (for example, 5 inches) that can transport chickens from the waste chicken inlet to the storage tank of the suction pump car, and the work cart is equipped with an engine generator, hydraulic unit, etc. on a self-propelled four-wheel carriage. In addition, it is equipped with a multi-stage lifting device that is fixed vertically with a work table fixed, supports the tip of the suction hose at the upper end of the lifting device, and fixes the connection of the suction hose to the rear end of the carriage Travel forward and backward through the path between the cages.
A hose reel cart is a cart with a caster supported by a rotary take-up reel, and is used exclusively for extending a hose.
The suction pump vehicle includes at least one disinfection tank with a built-in heater and a deodorizing filter in addition to the suction pump and the collection tank with a filter for removing feathers, so that the surrounding hygiene and environment are ensured.

The present invention travels through a narrow passage in a poultry house and can easily aspire and harvest waste chickens in a multistage cage with a small number of people and collect thousands of waste chickens per hour. In addition, the collection bags that tend to be unsanitary are not used, and the discharged air is sanitized and deodorized, so it is hygienic and there is no concern about environmental pollution.

The device of the present invention is used by being connected to a passage 5 in a poultry house as shown in FIG.
The work cart 10 is shown in FIGS. 4 to 8, and includes a work table elevating device 15 at a front portion on a frame 14 of a four-wheel self-propelled carriage having drive wheels 11 and 12 and driven wheels 13 and 13, and power at a rear portion. A device 16 is provided and a hose H is held in the center.

The elevating device 15 includes a first cylinder 17 suspended from a frame, a second cylinder 18 elevating along this, and a support column 19 having a work table 20 attached to the lower end.
In the first cylinder 17, the bottom clevis 21 is pin-coupled 22 to the frame 14, and the side wall and the frame are hooked to the link bar 23 and fixed vertically. Reference numeral 24 denotes an extension rod, and reference numeral 25 denotes a guide rail fixed to the left and right side walls of the cylinder.
The upper end of the second cylinder 18 is connected to the tip of the rod 24 of the first cylinder via a connecting member 26, and a roller U-shaped holder 27 is fixed to the lower end. A pair of rollers 28 and 29 are disposed opposite to each other inside the holder, and each rolls with the guide rail 25 of the first cylinder interposed therebetween.

Reference numeral 30 is a guide rail fixed to the left and right side walls of the second cylinder, 31 is an extension rod, and the upper end of the worktable support column 19 is connected and integrated by a connecting member 32 at the tip. 33 is a U-shaped holder with a roller fixed to the lower end side of the support column 19, and a pair of rollers 34 and 35 sandwiching the guide rail 30 of the second cylinder are supported on the inner side.
With the above configuration, the second cylinder 18 moves up and down along the first cylinder 17, and the worktable support column 19 moves up and down smoothly along the second cylinder 18.
The tip of the hose H is inserted and operated from a narrow inlet (not shown) of the cage. 36 is a hose band, and 37 is a handrail-like fixing tool. The tip of the hose is preferably opened in a trumpet shape. The middle of the hose is supported at the center of the carriage, and the hose joint 38 at the rear end is fixed on the carriage. The power unit 16 includes an engine generator 40 and a hydraulic unit 41 that incorporates an electric motor, a hydraulic pump, and a direction control valve.

When the poultry house is relatively small, the work cart can be used only. However, when the length of the passage is 20 m or more, the hose reel cart is used as an extension.
9 to 11, reference numeral 50 denotes a cart with a caster, and a reel stand 52 is erected on a base plate 51 to support a hose winding drum 53. Reference numeral 54 denotes a bearing support device. An annular rack 57 is fitted on the outer periphery of the outer cylinder 56 fixed to the reel side plate 55 and meshed with the pinion 58.
59 is a brake motor with a clutch, which drives the drum when winding the hose, but is released when the hose is pulled out as the work cart advances, and the reel rotates freely.
A hose joint 60 connected to the joint 38 of the work cart is attached to the front end of the hose, and the rear end 61 is connected to the core tube 62 passing through the center of the reel and communicates with the hose base 64 via the swivel joint 63. Reference numeral 65 denotes a power source such as an engine generator, and reference numeral 66 denotes a winding operation switch. Since the hose wound around the drum is usually 30 to 50 m / unit, a plurality of reel carts 50 are connected.

The heater temperature setting device is omitted. 79A and 79B are air diffusers, and 80 is a partition wall. Each disinfection tank may be installed separately, but it will be installed next to it in consideration of thermal efficiency.
Reference numeral 81 denotes an exhaust pipe, and a discharge fan may be provided.
With the above-described configuration, the feathers are removed, the discharged air is sterilized, and the deodorization is performed, so that a recovery operation without fear of environmental pollution is possible.

(Test example)
The work cart shown in FIG. 4 is connected to a suction wheel equipped with a pump with a pump capacity of 40 m ³ / min and a maximum vacuum of −720 mmHg using a commercial hose with an inner diameter of 5 inches and an anti-static coupler. A total of 24 abandoned chickens (height 340 to 390 mm, mass 1.3 to 1.9 Kg) housed in the cages were sucked from the head side of the chickens with different hose lengths.
Although suction was performed with hose lengths of 10 m, 40 m, and 120 m, the transfer speed in the hose was 10 m / sec, and no difference depending on the hose length was observed. When abandoned chicken was sucked from the trunk side, it could stay in the hose for a few seconds, but there was no clogging of the hose, and there was no hindrance to continued operation. Harvested chickens in the collection tank were completely suffocated under reduced pressure.
